.Specification of Letters Patent.

Iatented Sept. 1, 1908.

application filed September 11, 1907. Serial No. 392,373.

To all whom'r'vt may concern:

Be it known that 1, JOHN ANDERSON, a

. citizen of the Dominion of Canada, and residing at No. 99 Bay street Nin the city of Hamilton, in the county of Wentworth, in the Province ofOntario, Canada, have invented a new and use'fiil Support forSliding-Door Tracks; and I do hereby declare that the following is afull, clear, and exact descrip balanced fit in the track, and is capableof sustaining greater weightof the door on account of its verticalposition in the track, and other advantages as will be more fully shownhereinafter. I attain these objects by the mechanism illustrated in theaccompanying drawing, in which:

, Figure 1, is a front elevation of section of ,a door with trackattached thereto. Fig.

2, is an end view of the same somewhat enlarged. Fig. 3, is a front viewof the track support detached. Fig. 4:, is a side'view of the. same.Fig. 5, is a side view of the track. Fig. 6, is a transverse section ofthe same. Fig. 7, is a cross section of a modification. of the same.

In the drawing A, represents a barn door. B, the track; formed earshaped, being largerat the top than the bottom, as clearly shown at Fig.6, and having a horizontal opening a, on the inner side, as shown inFigs. 2 5 and 6. C, Figs. 3 and 4, re resent front and side views resectively o the sup 'ort for the track B, w ich consists of an ova shapedbase plate b, having two bolt openings (1, d, at the top and a notch e,at the bottom for bolts f, to pass through, by which to secure saidplate to the building to be furnished therewith. Attached to the saidplate C, is an ear shaped projection 9, cast integral with it and formedwith a terminal head that has a roundedtop and bottom one smaller thanthe other to correspond with the shape of the track B. The saidprojection is provided with a notch h, at the top portion and a similarone h, at the bottom, into which the bent ends 2, 3, of the track B,enter and rest therein. r

D, D, are brackets attached to the door A, by bolts 76, as shown in Fig.1, for the purpose of carrying two pulleys. The top and larger one i, ismade to rest and run on the upper portion of the track B, and thesmaller one j,

is placed so as to run underthe said track B,

as shown at Fi 2.

It will be obs erved that the track B, whilepreferably made in the formshown at Fig. 6, may be modified somewhat in an oval shape as shown atFig. 7.

It will be seen that the object of forming the support C, in the shapeshown at Figs. 3 and 4 is for the ease, quickness and convenience thatthe head 9, can be inserted flat in the opening a, of the track, thenturned upright in the track as-seen inFig. 2, and bolted to the buildingto support the track. This plan has the advantage over a stationary orriveted support as my track support as hereinbefore mentioned can beinserted at any point of the track B, to still further strengthen y it,if there is a likelihood of its sagging, without driving the same in thetrack from the ends as in other devices for the same purpose.

The great advantage of my device r'or the purpose specified is thesaving of time, convenience of handling and effectiveness in operationas the supporting part 9, is in anu right position when it supports thetree and hence can bear more weight as it isin the best position forstrength and durability.

I am aware that supports have been used in a tubular track, but theyhave to be driven in from the end of the track, and have a horizontalbearing to support the track, which is objectionable as not possessingsufficient strength while my support has a vertical bearing inear-shaped track, which is capable of sustaining greater weight, is moredurable,

convenient and satisfactory in every particular.

Having thus described my device and its advantages, what I claim as myinvention and desire to secure by Letters Patent, is,

1. The combination of a track consisting of a hollow member providedwith a longitudinal slot in its rear and extending from one end thereofto the other, with a plurality of supporting brackets therefor, eachbracket consisting of a base, a shank extending outwardly therefrom, anda head on the outer extremity of the shank and of less thickness thanthewidthof the slot of the track for insertion therein LIL( 1 1'CI11OVLltherefrom, the head being of such length as to interlock iii 5 the trackwhen the bracket is turned to throw the head transversely to the slot,-and the shanks of the brackets being of such length as to space thetrack a suflicient distance from the Wall to Which the track is se- 1cured for permitting a bracket to be applied to tlie track While thelatter is inposition.

2. A track supporting bracket comprising a base, a shank secured to andprojecting outwardly therefrom, and a head on the shank and rounded atits to and bottom, 15 said shank having recesses in its top and bottomsurfaces at a point immediately adjacent the head.

Hamilton, Ontario the 28rd day of August JOHN ANDERSON. Signed in thepresence .of
